2028 Democratic VP Nominee Odds: How the Market Splits the Party's Bench

The 2028 Democratic VP nominee market and the 2028 Democratic presidential nominee market share almost their entire field. Of the 45 names priced for vice president, 43 also trade on the presidential board. Comparing the two prices for each person shows how the market is sorting the party's bench: some names are priced primarily as the top of a ticket, and others primarily as a running mate.

2028 Democratic VP Nominee Odds Today

As of October 13, 2026, no name trades above 10c on either venue. The leading tier on Kalshi and Polymarket:

The VP board carries roughly $3.3M in lifetime volume. The presidential board it depends on carries more than $1.5B.

Top of the Ticket Versus the 2028 Democratic VP Nominee Slot

Placing each person's presidential price beside their vice-presidential price separates the field into two groups.

The first five names are priced higher for the presidency than for the second slot. Jon Ossoff is the clearest case: 17c on Kalshi to be the presidential nominee, 5c to be the running mate. Gavin Newsom trades at 14c for president on both venues and 2c to 3c for vice president.

The second five run the other way: each is priced higher for vice president on Kalshi, and on Polymarket in every case except Pete Buttigieg, who trades at 5c for both. James Talarico is priced at 3c and 2c for president and 7c and 5c for vice president. Wes Moore trades at 2c for president on both venues and 6c for vice president on both. The market is treating these names as likelier to be chosen than to do the choosing.

Why the 2028 Democratic VP Nominee Price Moves With the Presidential Board

The two outcomes cannot both happen for the same person. Whoever wins the presidential nomination is not the vice-presidential nominee, so a candidate rising on the presidential board is, in part, moving out of the running-mate pool. For the names priced primarily as presidential contenders, that caps how high their VP price can climb.

The presidential nominee also makes the vice-presidential choice. That makes the presidential board the main driver of this one: each shift among the presidential front-runners changes which running mates are plausible, through regional, ideological and personal considerations that are specific to whoever wins.

Where Kalshi and Polymarket Differ on the 2028 Democratic VP Nominee

Almost all of the money is on Kalshi. Across the field, Kalshi legs account for about $3.2M of lifetime volume and Polymarket legs about $103K, roughly 97% to 3%. Kalshi's leading legs individually hold between $77K and $304K.

On the shared names, the two venues mostly agree. The largest gaps among the leaders are on Elissa Slotkin, at 10c on Kalshi and 7c on Polymarket, and Pete Buttigieg, at 8c and 5c. Given how much thinner the Polymarket side is, and that some Polymarket legs carry wide gaps between bid and offer, those differences are as consistent with depth as with disagreement.

When the 2028 Democratic VP Nominee Market Resolves

The market resolves to the first individual formally nominated by the Democratic Party for vice president in the 2028 presidential cycle who accepts the nomination. Kalshi lists a resolution date of November 7, 2028 and Polymarket November 8, 2028. In practice the outcome is known once the presidential nominee names a running mate and the convention formally nominates them, well ahead of those dates.

Key Factors for the 2028 Democratic VP Nominee Market

• The presidential nomination:** the nominee chooses the running mate, so the presidential board leads this one.
• The split between groups:** names priced higher for president lose running-mate probability as their presidential odds rise.
• Presidential campaign entries:** a declared presidential run moves a name's price on both boards at once.
• Depth on Kalshi:** about 97% of the volume, so Kalshi sets the level and Polymarket is a thinner second quote.
• The running-mate announcement:** effectively settles the market ahead of the formal nomination.
